I'd counter that jobs are actually in pretty good shape overall at the moment -- unemployment is low and while wages are still behind where they should be, that has slowly started on the upswing also in the last few months. The problem is that the recovery hasn't been felt, at all, by the small single industry towns in the rust belt that were devastated when the factory, the steel mill, the mine, etc shut down for whatever reasons -- leaving huge parts of the country hopeless, jobless, and devastated by meth use and the diseases (hep and HIV) that run in it's wake.
The solutions to this involve widening the social safety nets, and investments in education, vocational retraining, and drug rehabilitation and education -- and those aren't things that are part of any Republican agenda that has existed in any of our lifetimes. I'd imagine that Mike Pence's term as Indiana governor might serve as a decent predictor for the Trump administration's approach to these issues -- and as an Indiana resident, I can tell you that this is a huge reason that he is Trump's VP in the first place. Pence is hated here because of his response to these problems.
